T 0 all whom it may concern:

Be it known that I, CHARLES F. CRANDALL,

of New York, have invented certain new and useful Improvements in Adjustable Hangers for Type-Writer Type-Bars; and I do hereby "leclare that the following is a full, clear, and exact description thereof,. which will enable others skilled in the art to which it appertains to make and use the same, reference being had to theaccompanying drawings, and to the letters of reference. marked thereon;

which form part-of this specification.

improved hanger for the type lever or bar of a-typewriter whereby the type bar may be conveniently adjusted to its hearings and the in the frame bar. For securing the hangerarm adjusted relative to the (paper roll or tothe frame bar there is provided a bolt 19, or replaced which passes through the bar 16, passing in part through the socket 17 and in part through ahole perforating the balance of the roved construction shown in its relative r'ebar. The bolt 19 is loosely connected tothe part 18 by entering a-socket providedin the end of the base part 18 and being secured Fig. 2 is an enlarged therein by a pin .20. On the rear side of the frame bar 16 the bolt will be provided with'a nut 21 and preferably with a Washer as Fig. 3 is .a plan view of the part shown. The ivotal end of the type bar 5 is Fig. 4 is an inside view of provided wi't one of the walls or parts of the hanger.

Extending between the .of what may be termed the base end or part platen and the whole remove with facility.

For operating the type there is rovided a bellcrank lever 9 connectindicates a spring for lifting the key lever and assisting in returning the type bar to its normal position. 15 indicates a pad'on which the end of the typebar is adapted to rest in its normal position; The particular details of all these parts is-not material as my im- HANGER FOR TYPE-WRITER TYPE-BARS.

! provements hereinafter described are equally l useful on that class of typewriters in which of Rich, in the county of Herkimer and State 1 the type bars normally are in a suspended position and-strike inwardly and upwardly. A support for the type bar hangers isshown in the frame bar 16, which has a semisph'erical socket 17, there being as manysockets 17 provided as are required for 'mounting the desired number of type bars. The hanger 18 consists of two main side walls ls spaced apart to receive the pivotal end of the type bar and secured to the hanger base piece 18 conveniently by a pair of riv- The object of my invention is to provide an ets a as shown. The piece 18 is provided with a semispherical bearing end 18, which is received in and fits snugly in the socket 17 conical bearing projections walls of the hanger and threaded into each is Fig. 7 is a detail view showa screw 25 having ri ht and left hand threads ing the pivotalend of the ty 'e-bar.

Referring to the reference letters and figor boss 25 adapted to receive a wrenc 1. rotating the screw 25 in one direction or the other the walls 18 may be closed together o1 sprung apart whereby the type bar 5 may be ures in a more particular description, 5 invery nicely and accurately adjusted in. its

e ordinary bearings, which as. well known is veryimportant in a typewriter at this point. aper nut 21 securing the hanger 16 isloosened the ar. hanger may be adjusted to a limited amount in any direction whereby the osition of the ed by a justable connecting rod 10 with the t pa with reference to the p aten' may be' short arm of the type bar. The lever 9 is ch pivotall mounted In any suitable fixed supliearin as 11', and is connected bya anged to the desired position. When so adjusted the hanger will be firmly secured in its desired position by tightening the nut21 connecting ro 12 with a key lever 13. 14 In the'construction o'f hanger shown in Figs. 1 .to 6 inclusive, it is required that the pivotal end of the type ,barbe inserted in place between the plates 18 before the several parts of the hanger are secured to ether. In the form of construction shown in igs. '8 and 9 this is obviated by forming the hanger there is in two parts 27, 251 These parts include the scmispherical bearing part b, which engages in the socket inthe frame bar. For the purpose ol" securing the hanger in the socket provided a bolt having a seinispherl ical head 29 engaging in a seinispherical 1 socket 3U p,rovided partially in one part 28 and partially in the other part 27'. The seniispherical head. part of this hanger is adapted to be received in a seinispherical recess in the frame bar 16-as of the previously described construction, and the same is. adapted to be held and firmly clamped in any desired position by the bolt. 1t will be noted with referencetothis construction that when removed from the socket it can be en'- tirely takendown by removing the screw 25.

It is evident that other modifications and changes in and from the construction hereirr described may be made without departing from the spirit of my invention.

WVhat I claim as new and desire to secure by Letters Patent is:

1. A hanger for a t *pe bar having substantially semispherica bearing, a frame bar having socket to receive the bearing and a bolt engaging in the hanger and passing through the socket and the bar and arranged to bind the hanger to the bar, substantially as set forth;

2. A hanger for a type bar having sub-' stantially semispherical bearing, a frame bar having a socket to receive-the bearing, a bolt movably engaging the hanger and passing throughthe socket and frame bar, substan- I walls, a frame bar having a socket to receive the bearing, means for binding the hanger to the frame bar with the semispherical bearing engaging in the socket and means-for adjusting said side walls toward and from each other to adjust the bearings of the type bar in the hanger, substantially as set forth.

In witness whereof, I have afliXed my signature, in presence of two witnesses, this 6th day of July 1907.
